Mike,
Thanks. Great thought - but I'm trying to measure a J-Pole so it has 0 ohms DC resistance between center conductor and shield.
Some new information. I played some with it again this morning. When I first tried it with everything connected directly to the S11 connector it worked fine on both bands. gave me the results I expected. Adding the pigtail worked on 2 meters but not 440. Then it failed on 2 meters also, both with and without the pigtail.
I'm beginning to think perhaps the SMA connector is making intermittent contact with the board. I'll take it apart later and take a look but I'm not sure my eyesight will allow me to fix it.
73 es tnx agn
